Mouches Volantes, Eye Floaters

In ophthalmology, mouches volantes are free-floating particles in the eye´s vitreous which impair the eyesight of the person affected. The common English term for these is »eye floaters«.

Such opacities of the vitreous can have different causes; in most cases they are age-related rather than pathological. In bright light conditions, the shadows of these particles are projected onto the light-sensitive retina and thus become visible to the viewer as small rings, dots and strands which appear to »fly« through the visual field, following the eyes´ motions. Eye floaters are widely spread, in itself harmless and not effectively treatable with our current medical means.

This explanation of mouches volantes makes sense to us, even if we are not ophthalmologists, because it refers to our everyday realm of experience accessible with our intellectual mind.

Drinking Water in Empty Stomach is Healthy


It is popular in Japan today to drink water immediately after waking up every morning. Furthermore, scientific tests have proven its value. We publish below a description of use of water for our readers. For old and serious diseases as well as modern illnesses the water treatment had been found successful by a Japanese medical society as a 100% cure for the following diseases:

Headache, body ache, heart system, arthritis, fast heart beat, epilepsy, excess fatness, bronchitis asthma, TB, meningitis, kidney and urine diseases, vomiting, gastritis, diarrhea, piles, diabetes, constipation, all eye diseases, womb, cancer and menstrual disorders, ear nose and throat diseases.

METHOD OF TREATMENT
1. As you wake up in the morning before brushing teeth, drink 4 x 160ml glasses of water

2. Brush and clean the mouth but do not eat or drink anything for 45 minute

3.. After 45 minutes you may eat and drink as normal.

4. After 15 minutes of breakfast, lunch and dinner do not eat or drink anything for 2 hours

5. Those who are old or sick and are unable to drink 4 glasses of water at the beginning may commence by taking little water and gradually increase it to 4 glasses per day.

6. The above method of treatment will cure diseases of the sick and others can enjoy a healthy life.

The following list gives the number of days of treatment required to cure/control/reduce main diseases:
1. High Blood Pressure (30 days)
2. Gastric (10 days)
3. Diabetes (30 days)
4. Constipation (10 days)
5. Cancer (180 days)

Drinking water is good for health

This treatment method has no side effects, however at the commencement of treatment you may have to urinate a few times.
It is better if we continue this and make this procedure as a routine work in our life. Drink Water and Stay healthy and Active.

This makes sense .. The Chinese and Japanese drink hot tea with their meals not cold water. Maybe it is time we adopt their drinking habit while eating!!! Nothing to lose, everything to gain…

For those who like to drink cold water, this article is applicable to you.
It is nice to have a cup of cold drink after a meal. However, the cold water will solidify the oily stuff that you have just consumed. It will slow down the digestion.

Once this ‘sludge’ reacts with the acid, it will break down and be absorbed by the intestine faster than the solid food. It will line the intestine.
Very soon, this will turn into fats and lead to cancer. It is best to drink hot soup or warm water after a meal.

A serious note about heart attacks:

· Women should know that not every heart attack symptom is going to be the left arm hurting,
· Be aware of intense pain in the jaw line.
· You may never have the first chest pain during the course of a heart attack.
· Nausea and intense sweating are also common symptoms.
· 60% of people who have a heart attack while they are asleep do not wake up.
· Pain in the jaw can wake you from a sound sleep. Let’s be careful and be aware. The more we know, the better chance we could survive…

What Does Déjà vu Mean.. why it happens

Have you ever experienced a sudden feeling of familiarity while in a completely new place? Or the feeling you’ve had the exact same conversation with someone before?

This feeling of familiarity is, of course, known as déjà vu (a French term meaning “already seen”) and it’s reported to occur on an occasional basis in 60-80% of people. It’s an experience that’s almost always fleeting and it occurs at random.

So what is responsible for these feelings of familiarity?

Despite coverage in popular culture, experiences of déjà vu are poorly understood in scientific terms. Déjà vu occurs briefly, without warning and has no physical manifestations other than the announcement: “I just had déjà vu!”

Many researchers propose that the phenomenon is a memory-based experience and assume the memory centres of the brain are responsible for it.

Memory systems

The medial temporal lobes are vital for the retention of long-term memories of events and facts. Certain regions of the medial temporal lobes are important in the detection of familiarity, or recognition, as opposed to the detailed recollection of specific events.

It has been proposed that familiarity detection depends on rhinal cortex function, whereas detailed recollection is linked to the hippocampus.

The randomness of déjà vu experiences in healthy individuals makes it difficult to study in an empirical manner. Any such research is reliant on self-reporting from the people involved.

Glitches in the matrix

A subset of epilepsy patients consistently experience déjà vu at the onset of a seizure – that is, when seizures begin in the medial temporal lobe. This has given researchers a more experimentally controlled way of studying déjà vu.

Epileptic seizures are evoked by alterations in electrical activity in neurons within focal regions of the brain. This dysfunctional neuronal activity can spread across the whole brain like the shock waves generated from an earthquake. The brain regions in which this electrical activation can occur include the medial temporal lobes.

Electrical disturbance of this neural system generates an aura (a warning of sorts) of déjà vu prior to the epileptic event.

By measuring neuronal discharges in the brains of these patients, scientists have been able to identify the regions of the brain where déjà vu signals begin.

It has been found that déjà vu is more readily induced in epilepsy patients through electrical stimulation of the rhinal cortices as opposed to the hippocampus. These observations led to the speculation that déjà vu is caused by a dysfunctional electrical discharge in the brain.

These neuronal discharges can occur in a non-pathological manner in people without epilepsy. An example of this is a hyponogogic jerk, the involuntary twitch that can occur just as you are falling asleep.

It has been proposed that déjà vu could be triggered by a similar neurological discharge, resulting in a strange sense of familiarity.

Some researchers argue that the type of déjà vu experienced by temporal lobe epilepsy patients is different from typical déjà vu.

The déjà vu experienced prior to an epileptic seizure may be enduring, rather than a fleeting feeling in those who don’t have epileptic seizures. In people without epilepsy the vivid recognition combined with the knowledge that the environment is truly novel intrinsically underpins the experience of déjà vu.

Mismatches and short circuits

Déjà vu in healthy participants is reported as a memory error which may expose the nature of the memory system.Some researchers speculate that déjà vu occurs due to a discrepancy in memory systems leading to the inappropriate generation of a detailed memory from a new sensory experience.

That is, information bypasses short-term memory and instead reaches long-term memory.

This implies déjà vu is evoked by a mismatch between the sensory input and memory-recalling output. This explains why a new experience can feel familiar, but not as tangible as a fully recalled memory.

Other theories suggest activation of the rhinal neural system, involved in the detection of familiarity, occurs without activation of the recollection system within the hippocampus. This leads to the feeling of recognition without specific details.

Related to this theory, it was proposed that déjà vu is a reaction of the brain’s memory systems to a familiar experience. This experience is known to be novel, but has many recognisable elements, albeit in a slightly different setting. An example? Being in a bar or restaurant in a foreign country that has the same layout as one you go to regularly at home.

Even more theories exist regarding the cause of déjà vu. These span from the paranormal – past livesalien abduction and precognitive dreams – to memories formed from experiences that are not first-hand (such as scenes in movies).

So far there is no simple explanation as to why déjà vu occurs, but advances in neuroimaging techniques may aid our understanding of memory and the tricks our minds seem to play on us.

Dynamic Tower

The Dynamic Tower (also known as Dynamic Architecture Building or the Da Vinci Tower) is a planned 420-metre (1,378 ft), 80-floor moving skyscraper in Dubai, United Arab Emirates, designed by architect David Fisher. The 68-story tower will feature floors that can be individually rotated via voice commands. Similar to the Suite Vollard completed in 2001 in Brazil, each floor
will be able to rotate independently. This will result in a constantly changing shape of the tower. Each floor will rotate at maximum of 6 metres (20 ft) per minute, or one full rotation in 90 minutes. It will be the world’s first prefabricated skyscraper with 40 factory-built modules for each floor. The entire tower will be powered from wind turbines and solar panels. Enough surplus electricity should be produced to power five other similar sized buildings in the vicinity. The turbines will be located between each of the rotating floors.

The Invisible Car By Mercedes

And Yes it is the “INVISIBLE” what you read is right! The much awaited super invisible car finally made by the Mercedes Benz. Its not a fantasy any more, and they have done it. Its amazing to hear that we are finally sitting in the world where such technology now really exist!

They have put down some super technology of LED to produce a invisible car. All they have done is covered all of the car with LED and given cameras at the sides so that the camera takes image of the other side and make it appear on LED on the other side, making a phenomenon of appearance of nothing in between.

Sound travels through water 3 times faster than through air.

A square piece of dry paper cannot be folded in half more than 7 times.

Air becomes liquid at about minus 190 degrees Celsius.

Liquid air looks like water with a bluish tint.

A scientific satellite needs only 250 watts of power, the equivalent used by two hour light bulbs, to operate.

The thin line of cloud that forms behind an aircraft at high altitudes is called a contrail.

Radio waves travel so much faster than sound waves that a broadcast voice can be heard sooner 18,000 km away than in the back of the room in which it originated.

A US ton is equivalent to 900 kg (2000 pounds). A British ton is 1008 kg (2240 pounds), called a gross ton.

Industrial hemp contains less than 1% of THC, the psychoactive component of marijuana.

Since space is essentially empty it cannot carry sound. Therefor there is no sound in space, at least not the sort of sound that we are used to.

The Space Shuttle always rolls over after launch to alleviate structural loading, allowing the shuttle to carry more mass into orbit.

The word “biology” was coined in 1805 by Jean-Baptiste Lamarck.

Most of the air is about 78% nitrogen gas. Only 21% consists of oxygen. The remaining 1% consists of carbon dioxide, argon, neon, helium, krypton, hydrogen, xenon and ozone.

Argon is used to fill the space in most light bulbs. Neon is used in fluorescent signs. Fluorescent lights are filled with mercury gas.

Hydrogen gas is the least dense substance in the world.

Water expands by about 9% as it freezes.

The surface of hot water freezes faster than cold water but the rest of the water will remain liquid longer than in a cold sample.

The smallest transistor is 50-nanometres wide – roughly 1/2000 the width of a human hair.

A compass does not point to the geographical North or South Pole, but to the magnetic poles.

The double-helix structure of DNA was discovered in 1953 by James Watson and Francis Crick. The length of a single human DNA molecule, when extended, is 1.7 metres (5 ft 5 in).

In a desert, a mirage is caused when air near the ground is hotter than air higher up. As light from the sun passes from cooler to warmer air, it speeds up and is refracted upward, creating the image of water.

The typical bolt of lightning heats the atmosphere to 50,000 degrees Fahrenheit.

An electric oven uses one kilowatt-hour of electricity in about 20 minutes, but one kilowatt-hour will power a TV for 3 hours, run a 100-watt bulb for 12 hours, and keep an electric clock ticking for 3 months.
